Anyone experienced any unusual noises from the brake boost pump? My '05 (49k miles) is starting to make some funny sounds - mainly if it has been sitting for a couple days or if it is really cold out. Performance has been normal and when it is warmer it sounds normal. I have another year on the 6/75 warranty so I'm not too worried about it but just curious if anyone has experience anything with theirs.

Thanks

 

I do, occasionally, but not regularly. If it starts all the time, then I'll worry.

A few times, it has run longer than normal too when I unlock doors.

I'm at 104,000 miles in my 2005.
